33. Renault Z.E.

Debut: Paris Motor Show
Year: 2009
Complex Says: You know, we've been wondering when carmakers are going to do away with side mirrors and just install cameras. It would reduce wind drag, resulting in better gas mileage. Renault did just that with its Z.E. concept. Made to work with the Better Place charging-station project, the Z.E. uses LED for its headlights and is coated in paint that reflects heat.
